Answer: 47
Step-by-step explanation:
replace r by 4 and n by 5
8(4)+3(5) = 47
35/330 = 7/66. As both the numerator and denominator could be divided by 5

Answer:
cone: 138.16 in²
pyramid: 352 m²
Step-by-step explanation:
Use the appropriate formula from your list of area and volume formulas.
<u>Area of a Cone</u>
A = πr(r +h) . . . . . where r is the radius and h is the slant height
The radius is half the diameter, so is 4 inches.
A = π(4 in)(4 in + 7 in) = 44π in² ≈ 138.16 in²
__
<u>Lateral Area of a Square Pyramid</u>
A = 2sh . . . . . where s is the side length of the base and h is the slant height
A = 2(8 m)(22 m) = 352 m²
